Ancient slabs beneath Arctic and surroundings: Izanagi, Farallon, and in-betweens
A detailed 3-D tomographic model of the whole mantle beneath the northern hemisphere (north of ~ 30°N latitude) is obtained by inverting a large...

Shallow tectonic tremor activities in Hyuga-nada, Nankai subduction zone, based on long-term broadband ocean bottom seismic observations
The study of slow earthquake activity, which occurs in the shallow and deep sides of seismogenic zone, is crucial for understanding subduction zones,...

Tectonic Setting, Emplacement and Petrological Сharacteristics of the Qazan Granitoids: Evidence for the Neo-Tethyan Subduction, Urumieh‒Dokhtar Magmatic Arc, Iran
AbstractThe Qazan granitoid pluton (South of Kashan, Iran) is situated in the central part of the Urumieh–Dokhtar Magmatic Arc. The plutonic body...

Evidence of Subduction of the Paleoproterozoic Oceanic Crust in the Khapchan Belt of the Anabar Shield, Siberian Craton
Granulite complex on the left side of the Bol. Kuonamka River, below the mouth of the Khapchan River, is composed of melanocratic and mesocratic...

Petrology and geochemistry of the Pan-African high-K calc-alkaline to shoshonitic–adakitic Bapé plutonic suites (Adamawa-Yade block, Cameroon): evidence of a hot oceanic crust subduction
The 60 km-long Pan-African Bapé massif intruded in the Adamawa-Yade Archaean block is an excellent case for the study of subduction–collision-related...

Petrogenesis and tectonic implication of lavas from the Yap Trench, western Pacific
We present major and trace element data of lava recovered from the northern Yap Trench in the western Pacific and discuss their petrogenesis and...

Large Active Faults and the Wharton Basin Intraplate Earthquakes in the Eastern Indian Ocean
In recent years, great earthquakes occurred within the Wharton Basin in the eastern Indian Ocean, and they have been associated with active faulting...

Cenozoic structural and tectonic evolution in the Western **hu Basin, East China Sea Shelf Basin
The Western **hu Basin (WXB), part of the East China Sea Shelf Basin (ECSSB), demonstrates distinct structural differences between different...

Tectonic BSR Hypothesis in the Peruvian Margin: A Forgotten Way to See Marine Gas Hydrate Systems at Convergent Margins
Along the Peruvian convergent margin, which is controlled by long-lived subduction erosion and primary productive coastal upwelling, gas...

Dehydration at subduction zones and the geochemistry of slab fluids
Subducting oceanic slabs undergo metamorphic dehydration with the increase of temperature and pressure during subduction. Dehydration is an essential...
-
The study of subduction channels: Progress, controversies, and challenges
The subduction channel is defined as a relatively thin and weak zone with coherent kinematics between the descending and overriding plates during...

Redox processes in subduction zones: Progress and prospect
Oxygen fugacity ( f O 2 ) is an intensive variable that describes the redox state of a system. By controlling the valence state of multivalent elements, f O...

Observations and modeling of flat subduction and its geological effects
Flat subduction refers to low-angle (<10°) or sub-horizontal subduction of oceanic slabs. Flat subduction is only recognized in ~10% of present-day...

Middle Miocene forearc alkaline magmatism in Amami-Oshima Island, central Ryukyu Arc: implications for paleoreconstruction of Shikoku Basin
During the middle Miocene, forearc alkaline magmatism occurred in the Outer Zone of Southwest Japan and the northern Ryukyu Arc, resulting in the...
